The study is based on accelerated stress aging and actual field results. Experiments are described which demonstrate that I2L circuit failure in humid ambients due to Au elelctrolysis will not occur because of low voltage operation. Failure rates less than 10 FITs for an LSI part (.001% failure per 1000 device hours) under normal stress over a 40 year life are predicted for the main population by accelerated bias temperature and bias humidity stress. Well behaved current gain (ßu) under bias temperature step stress indicates that Ou degradation will not be a significant failure mechanism. At this writing, more than 60 million device hours have been accumulated for LSI chips in specific applications with no reported chip failures. This field result firmly supports accelerated stress reliability predictions.","PeriodicalId":428300,"journal":{"name":"14th International Reliability Physics Symposium","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114509552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this application, the reliability of the NiCr fuse can be considered to consist of two parts, that of the unfused and the fused resistor link. The reliability of unblown NiCr registors has been reported as excellent, when the resistors are properly fabricated and operated within well-defined specifications .[1,2,3] t The reliability of blown resistors is directly related to the probability of healing or \"growback\" occurring. [4] However, this can be minimized by fusing the resistors under proper blowing conditions. Although the reliability of fused NiCr resistors has been established, fusing mechanism has not, and is at presentonly speculation.","PeriodicalId":428300,"journal":{"name":"14th International Reliability Physics Symposium","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127121838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
